近代黄河水下三角洲底坡土体的差异侵蚀及土工特性
The Differential Erosion and Geotechnical Properties
of the Slope Soil on the Modern Huanghe Subaquous Delta
摘要
Abstract
After analysing the acoustic data and the difference blocks' geotechnical data of the modern Huanghe estuary, we find that the differential erosion and failure behvior of soil in the slope are controlled by sedimental geotechnical properties: The counter-failure ability of soil with a low clay content(<10%), high water content(30%～45%) and large void ratio(0.8～1.2) is weaker; the soil breakage will form collapse; The soil which has a high clay content (>20%), high water content(>45%) and large void ratio(>1.2) can slide and form surface disturbance bodies; and the soil which has a middle clay content(<20%), middle water content(20%～30%) and small porosity ratio(<0.8) has stronger counter-failure abilities and can be preserved to form monadnocks. Geotechnical properties will be changed after breakage, the water content and porosity ratio will decrease, the wet density and strength will increase, and the abilities of counter-breakage will strengthen, hence the slope stability will enhance.关键词
